Kate Hudson celebrated her 37th birthday with a meditation circle, plus more news

Last fall, Jessica Chastain proudly posted a Facebook video that showed her brush with the Queen of Pop onstage in Prague. Wait, maybe "brush" is too soft of a word. "I spanked Madonna and I've [got] video to prove it," Jessica wrote, sharing a clip from the concert where the singer had brought her up onstage for the song "Unapologetic B----." On "Ellen" this week the actress dished on the experience, and she still sounded star-struck. "They just said I had to climb this ladder and one of the dancers reached their hand out to me, pulled me on stage and then I did this whole dance routine with her, sort of," Jessica said. "I didn't even remember my name. I was so shy and even like the look on my face I look really uncomfortable and then Madonna gets down on her knees." Ellen asked if Madonna had requested a spanking, to which Jessica replied, "No! But that's what one does at a Madonna concert. … 'The funny thing is at that as I started to do it, you can tell by my face that I don't know what I should be doing and all the looks on the dancers faces behind are like 'she's touching Madonna!'" In the end, though, the spanking went over just fine -- Jessica could tell because Madge bestowed a thank-you treat on her guest. Said Jessica: "She handed me a banana afterwards."
